Answer: A
Step-by-step explanation:
1. Swap x and y.
2. Solve for the new y.
Add 8
Divide by 2.
Extract the square root.
AnsweTo see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them. If the reduced fractions are all the same, then you have proportional ratios.r:
Step-by-step explanation:
SOLUTION
The function given is
The domain of a function is the set of input values (x-values) for which the function is defined or real.
To obtain the domain of the function above, we need to solve the expression in the square root.
Take square root of both sides we have
Hence, the domain becomes
Domain is [-√7,√7]
Similarly, for th range of f(x) we have
Therefore
Range is [0,√7]
Answer:
The answer is B.
Step-by-step explanation:
You have to substitute x = 2, into the equation of y :
$65.40 multiplied by .15 is equal to $9.81
$65.40 + $9.81 = $75.21
